That mask retains 100% of the bits (if a "short" is 16 bits), so it
effectively does nothing.  That's a waste of cycles if the masking isn't
optimized away.  I don't get how this shuts up the RTC unless this construct
was specifically created as a workaround.

Could you turn off RTC, especially since C++ (and C) are deliberately
non-RTC languages?
